Postgres 数据库在重启后崩溃,尝试了几乎所有的方法,包括重新安装 postgres。它不会在 ubuntu 14.04 上启动,
$ systemctl status postgresql@9.6-main.service

在 Ubuntu 14.04 上安装 snap 后,我遇到了同样的错误。它是从 systemd 安装一些部分并破坏了 postgresql init 脚本。
您需要--skip-systemctl-redirect在文件中向 pg_ctlcluster添加参数/usr/share/postgresql-common/init.d-functions
您需要更改的功能:
do_ctl_all() {
...
# --skip-systemctl-redirect fix postgresql No such interface 'org.freedesktop.DBus.Properties'
if [ "$1" = "stop" ] || [ "$1" = "restart" ]; then
ERRMSG=$(pg_ctlcluster --skip-systemctl-redirect --force "$2" "$name" $1 2>&1)
else
ERRMSG=$(pg_ctlcluster --skip-systemctl-redirect "$2" "$name" $1 2>&1)
fi
...
}
